check shown in Figure 1. The catch member comprises a housing 16 50 Figure 4 is a side elevational view of the depreferably formed of sheet steel, and as shown, vice illustrated in Figure 3. formed with longitudinally extended flanges 17 Figure 5 is a sectional view taken through a which are suitably apertured to receive the bolts portion of the door catch illustrated in Figure 14. The body of the housing is rectangular in 3, the section being taken on a plane indicated form and apertured with elongated openings 18 55 for the reception of supporting lugs or tongues formed in the plunger cradle. The central portion of the housing 16 is provided with an opening 19 to accommodate the re-entrant engagement of the plunger 15.

The spring bolts are supported in cradles 20 which embody a base portion 21, a wall 22 and narrow centrally disposed wall or post 23. The walls 22 and 23 are shouldered to form tongues or lugs 24 which are received in the apertures 18 and riveted therein upon assembly to effect the securement of the cradles within the housing 16. The spring bolts 25 comprise a rectangu-- lar block laterally proportioned to slide freely within the housing 16 and of suitable thickness for longitudinal movement within thecradles-20. In the central portion of each of the bolts 25 there is a slot 26, the end walls thereof being coordinated with the posts 23 to limit the longitudinal movement of the bolt. Intermediate the rear wall of the bolts 25 and the, end walls 22 of the cradles there are contractile springs which are provided to effect the yielding movement of the bolts within the housings. The cradles 20 are so positioned Within the housing 16 that the forward faces of the bolts will lie in contiguous relation in the center. of the openings 19. The faces of the plungers are arcuate in form, the forwardm'ost; portion thereof being provided with long sweeping arcs 27 to accommodate the entrance andready separation of the spring bolts upon application of the effort imposed thereon by'the plunger head 28 when the door is secured in its open position. The rearward-edges of the plungers' are formed: with acute radii 29 which grip the inner wallsof the plunger head 28 and prevent the dislodgment of the plunger under relatively light application of pressure. 1

As shown in Figures 7 and 8,the ,side walls of the spring bolts are formed with notched side Walls 30 which are arranged for engagement by a pair of'stop members or posts; 31. In, this structure a guideway for the bolts 25 is provided in addition to the. shoulders or stops as formed by the slots 26 described in the preceding form. As further illustrated in Figure '7 an adjusting screw 32 is provided in the rear flange 22 of the cradlesfthe screw being adapted to facilitate the spring tension desired upon the plungers 25.

The embodiment illustrated in Figures 9 and 10 comprises a single spring bolt 25 and includes a depending flange 33 which retains the plunger head 28 and which is employed in substitution for a second plunger 25 as heretofore described.

Referring to Figures 2, 11 and 12 it willbe seen that the plunger members are formed of the same headed structure and'that the engagement with the catch 15 is eifected in the same manner by the use of either. It will be further noted that the extended and angulated neck 34 of the catch 1512 will permit a limited movement of the door, that is, an opening at substantially a right angle, while the engagement of the plunger 15 will permit the door to be revolved to its fully open position.

Although the foregoing description is necessarily of a detailed character, in order that the invention may be completely set forth, it is to be understood that the specific terminology is not intended to be restrictive or confining, and that various rearrangements of parts and modifications of structural detail may be resorted to without departing from the scope or spirit of the invention as herein claimed.

I claim:

; 1. A latch assembly for hinged garage doors and the like comprising in combination with a plunger latch: a housing adapted to be secured to a support adjacent the door, a cradle secured to said housing, a slotted bolt mounted for snug sliding movement in said cradle, said cradle being provided with means engaging in the bolt slot for limiting the longitudinal sliding movement of the bolt, a spring in rear of said bolt for normally urging it toward latching position, the

latch extremity of said bolt being formed with of slotted bolts mounted for snug sliding mov'ement in said cradle toward and away from one another, said cradle being provided with projections which engage in the slots of the bolts and limit the longitudinal sliding movement of the bolts, springs disposed between the rear ends of said bolts and the rear end walls of the cradle for normallyurgingthe bolts, to latching position, means for adjusting the tension of said springs,

the adjacent end faces of the bolts being formed with arcuate surfaces, said plunger latch being secured to a doorand having a-relatively flat shank and an enlarged substantially oval-shaped head adapted to engage said surfacesand retract the bolts and be releasably held thereby.

3. A latch assembly for hinged garage doors and the like comprising a pair of bolt-guiding and supporting frames, a bracket housingadapted to be'secured to a support adjacent a door and support said frames at the desired angle relatively to a door, a pair of coacting latch bolts slidably mounted in said frames and havingparcuate end faces, springs in rear of said bolts for normally urging the latter to latching position, means for adjusting the tension of said springs, each "of the bolts being formed with arecess or cut-out portion, and limit stops associated with the housing and adapted to engage in saidrecesses orfcutout portions for limiting movement. of said bolts toward one another to thereby'maintaintheir latch ends spaced apart to facilitate reception of a latch plunger. y
